Description

[Detailed Description of the Invention] This invention provides an inexpensive and long-lasting multicolored uneven pattern board.
This involves a method for manufacturing multicolored uneven pattern boards that are intended to be manufactured continuously in a factory, and involves the use of acrylic emulsion-based fillers on the outer surface of a substrate made of lauan plywood or flexible board made of rubber synthetic resin. The sealant or sealant is applied to an appropriate thickness and dried to form a sealing coating layer or sealing coating layer, and forming the sealing coating layer or sealing coating layer. A cream-colored undercoat based on acrylic emulsion is applied to the outer surface with a porous rubber roller to an appropriate thickness, and at the same time, a small uneven surface is formed to create a cream-colored undercoat with a fine and small uneven surface. After constructing the coating layer, immediately apply a topcoat based on a white acrylic emulsion different from that of the undercoat layer to a large convex surface arranged in a pattern using a brush coater. A coating layer is formed, and this is dried to form an uneven patterned board in which large white convex surfaces are painted in a pattern on a cream colored fine uneven surface. According to the invention, a cream-colored undercoat layer with a pongee-sized uneven surface is coated on the outer surface of a substrate such as lauan plywood or a flexible board via a sealing or sealing layer. On the uneven surface of the undercoat layer, a cream-colored topcoat layer with a different white hue and protruding large convex surfaces formed in a lotus pattern is applied. A multicolor uneven patterned plate having large white convex surfaces painted in a pattern on a small uneven surface can be produced continuously in a factory, making it inexpensive and long lasting, which is extremely useful.

Conventionally, the uneven patterns used for the exterior and interior of buildings are either formed directly on the wall base at the construction site, or are made in a factory as a plate-shaped body with a pre-formed uneven pattern. There are two types that can be installed in a designated location. In any of these methods, it is difficult to create multiple colors by changing the colors of the concave portions 2 and convex portions 3 of the concavo-convex pattern board 1 shown in FIG. 1.

That is, when forming an uneven pattern at a construction site, first, paint or cement material 5 containing aggregate is sprayed onto the surface of the wall base substrate 4 using a mortar spray gun, and the uneven areas 2, 3 are formed on the surface of the base substrate. is formed, and while the surface is not solidified, use a roller to flatten the top of the convex portion 3, form small uneven surfaces 6, 6, and then apply colored paint 7 on top of it. Since it is sprayed over the entire surface, it is difficult and almost impossible to paint the recesses and protrusions in different colors.

In addition, when manufacturing an uneven pattern board in a factory, a slate board or a ceramic material is generally used as the substrate 4, and the uneven pattern is formed by embossing immediately after papermaking or mold making, and then the uneven pattern is formed. Since the surface is colored and painted, it is impossible to make the recesses 2 and protrusions 3 in FIG. 1 different colors.

Furthermore, even when a metal plate is used as the substrate 4,
Since a colored metal plate is used, it is impossible to make the concave portions 2 and convex portions 3 different colors because it has to be embossed to form a concavo-convex pattern. It is.

On the other hand, the invention of this application eliminates these drawbacks of the conventional methods.According to the invention of this application, it is possible to continuously produce a multicolor uneven pattern board in a factory without stamping it. This makes it possible to obtain something inexpensive and long-lasting, which is extremely useful.

Conventionally, a multi-layer pattern sprayed layer in which small and large base layers are mixed and distributed is laminated on the decorative surface of the base material, and a top coat layer is provided on top of the sprayed layer. Applying a base layer to the surface, applying a multi-layer pattern spray material on it in large and small chunks, then allowing the multi-layer pattern spray layer to be semi-dry or dry, then applying a top coat layer and drying it, or , the base layer is formed into a panel shape that can be connected, a base layer is applied only to the decorative surface of the convex part, and a spray layer with a pattern of 4 large particles mixed and distributed is applied thereon, and the spray layer is After semi-drying or drying, in order to fill the back side of the convex part with a core material or to apply ricin coating, a ricin coating surface is formed on the base surface, and then the ricin coating surface is coated with a color different from that of the coating material. It is known to spray paint sparsely and tightly into a convex lens shape and to press the top of the protrusion to form a flat top.

However, these three prior art inventions, like the invention of this application, apply a filler based on an acrylic emulsion to the outer surface of a substrate made of lauan plywood or a flexible board made of rubber, synthetic resin, etc. Or apply sealant to an appropriate thickness,
It dries to form a seal coating layer or a seal coating layer, and a porous rubber roller is used to apply a cream-colored undercoat based on acrylic emulsion to an appropriate thickness on the outer surface of the seal coating layer or seal coating layer. At the same time, an acrylic emulsion of a white color different from that of the undercoat layer is immediately applied to form a cream-colored undercoat layer having a concavo-convex surface with a small size of Tsumugi. Using a brush coater, a topcoat based on a large convex surface with a lotus pattern is applied to form a topcoat layer, which is then dried to form a cream-colored, finely uneven surface with white spots. It is different from a board with a concave-convex pattern painted on a large convex surface in a pattern, and of course the manufacturing method is different. A cream-colored undercoat layer with a lotus pattern is applied to the uneven surface of the thin 4. The uneven surface of the pongee small color of the undercoat layer is painted with a different white hue and patterned. A multicolored uneven patterned board with white large convex surfaces painted in a pattern on a cream colored small uneven surface coated with a top coat layer with large convex surfaces protruding from a lotus pattern. cannot be produced continuously in a factory to make it cheaper and last longer.

In contrast, according to this long-cherished invention, a filler or sealing agent containing acrylic emulsion as a main ingredient is applied to an appropriate thickness on the outer surface of a substrate made of a flexible board made of lauan synthetic resin, rubber, synthetic resin, etc. This is dried to form a sealing coating layer or sealing coating layer, and a cream-colored undercoat based on acrylic emulsion is applied as appropriate to the outer surface of the sealing coating layer or sealing coating layer using a porous rubber roller. A cream-colored undercoat layer having a fine and small uneven surface is formed by applying it to a thick layer and at the same time forming a small uneven surface, and then immediately using a white acrylic emulsion as the main agent, which is different from the undercoat layer. The top coat is applied with a brush coater in the form of a large convex surface arranged in a pattern to form a top coat layer, which is dried to form a large white convex surface on a cream colored fine uneven surface. By configuring an uneven pattern board painted in a pattern, it can be applied to the outer surface of a board such as a lauan plywood flexible board through a filler or seal coating layer.
A cream-colored undercoat layer with a lotus pattern on the fine and small uneven surface is applied, and a different white hue is applied to the fine and small uneven surface of the undercoat layer to form a lotus pattern. A multicolored uneven pattern board with large white convex surfaces painted in a pattern is continuously applied to a cream colored fine uneven surface coated with a topcoat layer with large convex surfaces. It is very useful because it can be manufactured in a factory, which makes it cheaper and lasts longer. Examples of the invention of this application will be described below.

A white top coat, which is different in hue from the undercoat, is coated with a brush coater to a thickness of 0 to 25 mm (wet) in a large size. The convex surfaces 12, 12... are applied in a pattern and dried to a semi-dry state to form the top coat layer 11. While dripping, use a rotating metal roller to press the convex top portion of the large convex surface 12 of the top coat layer 11 to make it flat, or By grinding with sandpaper or other abrasive material or by embossing to make it flat, a so-called head cutting process is applied, and large white convex surfaces are painted in a pattern on cream-colored fine and small uneven surfaces. 2
Colored uneven pattern boards are manufactured.

Furthermore, in order to improve weather resistance and gloss, or to make it difficult for dust and dirt to adhere, a clear coat such as acrylic urethane clear is sprayed as a top coat after the head cutting process to form a clear coating layer 13. Make it compose. At this time, when applying the top coat layer, it is also possible to manufacture multi-colored uneven pattern boards in three or four colors by increasing the number of brush coaters or spray guns and spraying paints of different hues. It is extremely useful.
